SPECIFICATION forming part of Letters Patent No. 731,969, dated J une 23, 1903 Application filed August 20, 1902. Serial No. 120,370. (No model.)

To all whom it may concern:

Be it known that LTHEODOR SULIKX, a citizen of the United States of America, residing at Duquesne, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Windows, of which the following is a specification, reference being had therein to the accompanying drawings. 7

This invention relates in general to new and usefulimprovements in windows, and relates more particularly to window-locks.

The invention has for its object the provision of novel means whereby a window-sash may be easily raised and lowered and looked at any desired point.

Another obj eet of the present invention is to provide new and novel means whereby a window-sash may be tilted at any desired angle and securely locked in position.

A still further object of my invention is to provide a new and novel form of locking mechanism that will act as a double lock and releasing mechanism, the double lock first lockin g the window-sash in the tilting or pivotally-secured sash-frame and also serving as locking means to securely retain the sashframe in any desired tilted position and performing the function of releasing mechanism by depressing the latch-bolts that serve the purpose of retaining the sash-frame and sash in proper position.

The invention further contemplates to provide a window-lock of this character that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

lVith the above and other objects inview the invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views,in which Figure l is a perspective view of my improved window. Fig. 2 is avertical sectional View thereof, showing, in dotted lines, the tilt ed position of the sash and SLSh*flt1l16. Fig.3 is an enlarged frontview of the sash-frame and sash and locking mechanism and showinga fragmentary view of the window-frame hav-. ing the latch-bolt secured therein. Fig. l is a fragmentary perspective view of the sash, sash-frame, and locking mechanism, showing .the sash in the elevated and locked position.

Fig. 5 is an enlarged perspective view of the casing in which thelatch-bolt is secured and which carries the segmental cog-rack. Fig. 6 is a similar view of the latch-bolt. Fig. 7 is a view in perspective of the sash-guides and the bell-crank levers connected thereto.

In the drawings the reference-numeral 1 indicates the window-frame, and. 3 the lower sash. This lower sash 3 is slidably mounted in sash-guides 2, which receive the opposite vertical edges of the sash, as will be understood by reference to Fig. 4. These sashguides are pivoted to the window-frame at points intermediate their ends by pivots 2, which are secured to the inner faces of the vertical sides of theavindo w-frame and having their outer ends projecting through openings provided therefor in the respective guides, as illustrated in Figs. 1 and 8. In order to permit of the lower sash being elevated in a vei tical plane, I secure to one of the sides thereof a notched rack 17. This rack is engaged by the inwardly-projecting lug 18. This is formed integral with the lower arm of the bell-crank lever 9, said lever being pivoted to the upper end of the guide, as at 8. The upper arm of this bell-crank lever 9 extends across the sash at a point adjacent its upper edge and has its end pivotally connected, as at 10, to a second bell-crank lever 9, which lever is also fulcrnmed at a point intermediate its ends to the opposite guide 2. By reference to Fig. 4 it will be observed that one of the guides 2 is provided at a point adjacent its upper end with a cut-out portion 7, through which the lug 18 of the bell-crank 9 extends to engage the notches of the rack--17.

The operation of myimprovement thus far described is as follows: In order toraise the lower sash vertically and to secure the same in its adjusted position,.' the transverselyarranged arms of the bell-crank levers are pressed downwardly through the medium of a handle 11, which can be secured to either lever, which operation throws the lug 18 out of engagement with the rack 17. The window can then be raised, and when it has been raised to the desired position the transversely-arranged arms are again moved upwardly to the position shown in Fig. 1, whereupon the lug l8.will again be moved into engagement with the rack and the window prevented from lowering.

14L designates oppositely-arranged latchbolts, the same being formed with shanks 5 and mounted in casings 15, secured in recesses 4 in the window-frame at points adjacent the inner face of the lower sash, so that the outer ends of the respective latch-bolts will contact with the inner sides of the guides 2, and thereby prevent the same from assuming a tilted position. Formed integral with the face-plates 6 of the respective casings 15 areoutwardly-projecting segmental toothed racks 16, the function of which will be eX- plained in the following: At the lower end of each of the lower arms of the bell-crank levers I provide outwardly-extending lugs 12, which lugs perform a double function namely, to depress latch-bolts 14 and, further, to secure the sash in its tilted position. This operation is performed as follows: To tilt the sash, the transversely-arranged' arms of the bell crank levers are pulled downwardly, which movement, as will be apparent, forces the outwardly-extending lugs 12 outwardly, so as to depress the bolts 14-, thereby permitting the sash to be swung outwardly, and when the sash is swung outwardly to the desired angle the transversely-arranged arms of the bell-crank levers are depressed or pulled downward to a greater degree, whereby the lugs 1.2 will be thrown into engagement with the tooth of the rack 16. By reference to Figs. 1 and 6 it will be noted that the outer faces of the heads of the bolts let are inclined or beveled, so that when the transverselyarranged arms of the bell-crank levers are swung upwardly, so as to disengage the lugs 12 from the respective racks 16, the sash can be readily swung inward to its normal position, whereupon the latch-bolts will again spring outwardly and lock the sash against outward movement.

In the drawings I have shown my improvements as secured to but one sash. It would be apparent, however, that if it is so desired I can provide both the upper and lower sashes of the window with my improvement, thereby providing means whereby each sash can be swung outwardly or adjusted vertically. In Fig. 1, as a substitute means, I have provided the upper sash with guides 25,which are provided at their upper ends with outwardlyextending ears 26, through the medium of which the same are secured in position. One of these guides 25 is provided at its inner edge with a notch 27, which is engaged by the swinging-catch 28, pivoted to the upper sash, as is clearly shown in Fig. 1. This arrangement merely provides means for holding the upper sash in its closed position.

- l rogecting rearwardly from the upper rear edges of the sash-guides are the flanges 30, which are adapted, when the upper and lower sashes are in their normal or closed positions, to project beneath the upper sash and prevent the lowering thereof in the event of the" catch 28 being displaced.

From the foregoing it will be apparent that by providing a tilting lower sash the same can be readily cleaned or be employed for ventilating or preventing rain entering the room.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the window-frame and the upper and lower sash frames arranged therein, of pivoted guides in which one of the said sash-frames is mounted, and flanges formed integral with the said guides adapted to project beneath the upper sash when both sashes are in their closed positions.

2; The combination of a window-frame, a pair of guides pivotally mounted on the sides thereof, a'latch-bolt slidably mounted in the window-frame and normally engaging one of the said guides, a sash slidably mounted in the said guides, and a bell-crank lever pivotally mounted on one of the said guides and being adapted to operate the said latch-bolt, substantially as and for the purpose'specifled.

3. The combination with a window-frame of a pair of guides pivotally mounted 011 the sides thereof, one of said guides being provided with a cut-out portion, a sash slidably mounted in the said guides, a toothed plate secured to the said sash, latch-bolts secured in the window-frame and adapted to engage the respective guides, bell-crank levers pivoted 011 the guides, an inwardly-projecting lug carried by one of the said bell-crank levers and adapted to project through the cut-.

out portion of the said guide and engage the toothed plate of the said sash and means carried by the said bell-crank levers for forcing the said latch-bolts out of engagement with the said guides.

4:. The combination with a window-frame of a pair of guides pivotally mounted thereon, one of the said guides being formed with a cut-out portion, a sash slidably mounted in the said guides, a toothed plate secured to the said sash, a pair of bell-crank levers pivotally mounted on said guides and having their upper ends connected together, a lug formed integral with one of the said bellcrank levers, said lug projecting through the cut-out portion of the said guide and being adapted to engage the toothed plate of the said sash, latch-bolts mounted in the windowframe and adapted to engage the said guides, means secured to the ends of the lower arms of the said bell-crank levers for forcing the said latch-bolts inward, and toothed plates secured to the window-frame and adapted to be engaged by the last-named means for holding the sash in a tilted position.

5. The combination with the Windowframe, of a pair of guides pivotally mounted on the sides thereof, means for preventing the outward movement of said guides, a pair of bell-crank levers, one pivoted to each guide and being pivotally connected together, and being adapted to release the first named means, a sash slidably mounted in said guides, arack secured to said sash, and means carried by one of said levers for engagement with said 10 rack for holding the said sash in its adjusted position.

In testimony whereof I afiix my signature in the presence of two Witnesses.
